Latest Comment (June 7, 16:30 UT) : There are several active regions on the Sun just now (left and middle images). The image from the Swedish Solar Telescope (SST) on Tenerife (left) shows the so-called "granulation", cells of hot gas (hundreds of kilometres across) moving around near the visible "surface" of the Sun. The dark feature in the lower part of that image is a "sunspot", a region somewhat cooler than the surroundings. Venus is visible in the image from SOHO-LASCO (right), approaching the Sun from the left. While you are preparing for tomorrow's event, why don't you get into the right mood by listening to John Philip Sousa's Venus Transit March" from 1882?
